Capital Letters?

My program is supposed to read in strings and compare them to words in a "dictionary" (basically a spell checker). However, if a word starts with a capital letter, I'm supposed to change that letter to a lower case letter and check the word again.

How would I change just one letter in the string? I know how to change an individual letter, but I'm a bit lost when it comes to strings...
